Radian A-DAC 15 Ambidextrous Lower FDE | AR-15

Description

The Radian A-DAC 15 is a fully ambidextrous AR-15 lower receiver designed for builders who want serious ergonomics without compromise. Machined from billet 7075-T6 aluminum with an integral trigger guard and flared magazine well, this lower gives you complete control regardless of which hand you favor.

What sets this lower apart is Radian's patented A-DAC (Ambidextrous Dual Action Catch) system. If you're right-handed, you can lock the bolt to the rear by simply pulling the charging handle back, pressing the right-side magazine release button, then releasing the charging handle. This means you never have to take your hand off the fire control area to perform this task. For ambidextrous operation, you get a left-side magazine release and right-side bolt release, plus the Talon ambidextrous safety selector that works from both sides.

Build Quality That Shows

The fit and finish are genuinely impressive. This isn't a lower that cuts corners on machining tolerances. The billet construction gives you dimensional stability that translates to a tight-fitting upper whenever you assemble your rifle. The Cerakote FDE finish provides real corrosion resistance while maintaining a clean tactical look. Inside, you'll find Radian's SART (Self-Adjusting Receiver Tensioner) spring-loaded plunger that minimizes upper-to-lower wobble.

What You Get

This lower ships with everything needed to get started on your build: the Talon 45/90 ambidextrous safety selector, enhanced takedown pin set, and all proprietary hardware including the extended bolt catch and release paddles. The flared magazine well speeds up reloads in training or competition. Multi-caliber marked, so it runs 5.56 NATO and .223 Rem interchangeably.

Made for Builders

Whether you're putting together a rifle for range time, training, or a specialized build, the A-DAC 15 gives you a rock-solid platform with controls that actually work the way you'd want them to if you could design them yourself. It's the kind of lower that makes you realize how much standard controls can limit your natural movement and efficiency.
